Displaying Inventory Information
To view physical disk inventory information, select Inventory from the filtering list. The
inventory information appears as follows:
The following information is displayed:
Column Description
ID
Physical disk ID, as assigned by the system. Physical disks are
numbered contiguously during system installation beginning with 0.
Cage The drive cage in which the disk resides.
Position Location of the disk in the format: N:S:P (Node:Slot:Port).
Device Type
Indicates whether a physical disk is a Fibre Channel (FC), Nearline
(NL), or Solid State (SSD) drive.
Device Speed Speed of the specified disk. (RPM)
Note: The Device Speed number does not represent a rotational speed for the drives
without spinning media (SSD). It is meant as a rough estimation of the performance
difference between the drive and the other drives in the system. For FC and NL drives, the
number corresponds to both a performance measure and actual rotational speed. For an
SSD drive, the number is to be treated as relative performance benchmark that takes into
account in I/O per second, bandwidth, and the access time.
